Joaquim Rocha built a smart door sign using a Pixoo 16×16 pixel display connected to his calendar via iCal to signal his availability to his family while working from home. The Python script shows different states—busy with time remaining, upcoming meetings, free time with random images, or dimmed at night—helping his kids and wife know when not to disturb him.

Smoital is a UTC-based timekeeping system for Mars that uses 24-hour-40-minute days (Earth units) with intercalary shortened days to match Martian solar time while maintaining compatibility with existing Earth software and ISO8601 standards. The system strategically distributes shortened days throughout the Martian year to correct Mars' equation of time and enable daylight saving time support, serving as a practical bridge for initial Mars colonization before transitioning to Mars-centric systems.
